BEATlNG-ENGINE ROLL.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed August 14,1906. Serial No, 830.601.

To all whom, t may concern: r

Be it known that I, Monrnrnn R. RUST, a citizenzof thehUnited States, residing at Fuli ton, in the county of Oswego and Stateof l New York, have invented certain new and useful Improvements in Beating-Engine Rolls, of which the following is aspecificatioir My invention relates to beatingengine rolls, and has for its object the production of iiy-bars and means for securing them to the supporting parts, all of particular construction and arrangement, whereby the fly-bars are rigidly held in place and cannot vibrate during operation. Vhere the bars are held in the roll and free from vibration, the engine is found to be more eflicient in its beating of stock.

It is a further object of my invention to produce a beating-engine roll ha ving the especial features herein set forth from which any one or more iiy-bars broken in use may be removed and replaced, if desired, without disturbing the others.

I accomplish the stated objects b y fashioning and associating the parts as illustrated in the accompanying drawings, of which- Figure l represents all the elements assembled, certain of them being shown in vertical section. Fig. 2 is a face view of a fly-bar. Fig. 3 is an enlarged fragmentary transverse sectional view introduced to more clearly eX- hibit the means for securing the fly-bars. Fig. 4 represents a half-circular vertical section of my invention on line X X in Fig. I, and Fig. 5 is a like half-circular vertical section on line Y Y of Fig. l.

Like letters of reference indicate the same parts throughout.

Upon the main shaft A are secured the outer and intermediate heads or circular supporting-frames B and C. The outer heads B have the iianges t extending in the planes of the heads, and each head is provided with a number of lugs b', usually cylindrical, as best shown in Fig. 3, projecting from the blocks b2, that are formed integrally with the rim of the head B and project in the manner of gearteeth. The intermediate heads or partitions C possess also corresponding numbers of cylindrical lugs c, projecting from the integrallyformed and radially-projecting blocks c', such lugs and blocks being of the same form and arrangement as those constituting like parts of heads B.

The fly-bars are marked D. Each is constructed with a number of holes d and has the shouldered portions d at the ends.

The remaining elements and features of my invention are most conveniently described in connection with the explanation of the plan of assembling the parts and the inode of operation.

It will be observed in Fig. I that the heads B and O are arranged upon the shaft A at distances apart corresponding with the positions of the holes d,.with which the fly-bars are provided, as illustrated in Fig. 2. The holes through the fly-bars receive the lugs t and c, and the shouldered ends d engage the flanges b of the heads B. An inspection of Fig. 3 will show that the lugs do not extend entirely through the fly-bars and that there is also an interval between any fly-bar on a lug and the rear of the block b2 in front of it. Such intervals or spaces I fill with molten metal E, which cools and occupies the space, as shown. The metal E employed is ordinarily one that has a low melting-pointfor example, Babbitt metal-which may be rendered fluid again to oilect its removal and the release of any ily-bar without injury to the heads or other members. The metal E performs two o'l'lices. As illustrated in Fig. 4 and more clearly in Fig. 3, it fills up that portion of each fly-bar hole d not occupied by l the lug, as well as the space between the flybar and the block before it. Thus the metal E locks the fly-bar on the lug and equally locks itself in the space mentioned.

`Between the heads, as is customary in beating-engine rolls, there is inserted fillingbars of wood which swell when wet and are by such expanison held in place. I employ the wooden filling-pieces in my invention, and in order to more securely maintain them in position I construct the three separate pieces F, G, and II arranged lengthwise between the heads and occupying the spaces between the inner ends of the ily-bars, as shown in Fig. 5. In a degree these pieces are held in place bythe swelling, as usual but in addition I construct the outerlying relatively longer cap-pieces J, shown in Fig. I as extending outside the flanges l) of heads B and in Contact with the three relatively shorter pieces F, G, and II and secured to them by screws or nails as illustrated.

Again considering Fig. 3, there will be ICC IOS

noted two wedges K and L in the space mentioned as filled with soft metal. It is convenient, although not essential, when fixing the fly-bars in position to first wedge them in place and then to pour the molten metal in upon and around them.

The foregoing description and the drawings herein set forth four points at which each fly-bar is held; but for rolls that are intended for light work it is not necessary for the bars to be held, excepting at their outer ends-that is, by the lugs b.

Having now described my invention and explained the mode of its operation, what I claim is-- l. In a beating-engine roll, the combination with heads having radially-projecting portions leaving spaces between them, of ilybars arranged in the said spaces, the projecting portions of the said heads and the said fly-bars being provided with devices engaging each other, the said devices including anv orifice, and a filling of relatively soft metal adapted to fill the remainder of each space between the said projecting portions of the heads and to enter the orifice included in said engaging devices to prevent the disengagement of the said engaging devices of the iiybars and heads, substantially as described.

2. In a beating-engine roll, the combination with the heads having radially-projecting portions leaving spaces between them, of fly-bars arranged in the said spaces, the parts of the said'iiy-bars occupying the said spaces in the heads being provided with orifices, and a filling of relatively soft metal adapted to enter the said orifices in the fly-bars and the remainder of each of the spaces between the said projecting portions of the heads whereby the iy-bars are secured t0 the heads, substantially as described.

3. In a beating-engine roll, the combination with heads having radially-projecting blocks and circumferentially-projecting lugs, of y-bars having holes adapted to engage the said lug, and metal filling disposed between the ily-bars upon the heads whereby the disengagement of the said lugs and holes in the iiy-bars is prevented and the ily-bars secured to the heads, substantially as described.

4. In a beating-engine roll, the combination with heads having radially-projecting blocks and circumferentially-projecting lugs, of iy-bars having holes adapted to engage the said lugs, and a filling of metal having a relatively low melting-point and disposed between the fly-bars upon the headswhereby disengagement of the said lugs and holes in the said fly-bars is prevented and the fly-bars securedA to the heads, substantially as described.

5. In a beating-engine roll, the combination with heads provided with lugs, of flybars provided with holes adapted to engage the said lugs, the said lugs being constructed to extend only part of the way through the holes in the fly-bars, and metal iillinggdisposed between the iiy-bars upon the heads and engaging the holes of the fiy-b ars whereby the said filling is locked in place and the flybars are secured to the heads, substantially as described.

6. In a beating-engine roll, the combination with headsy provided with lugs, of flybars provided with holes adapted to engage the said lugs, the said lugs being constructed to extend only part of the way through the holes in the fly-bars, and metal filling having a relatively low melting-point disposed between the fly-bars upon the heads and engaging the holes of the fly-bars whereby the said filling is `locked in place and the fly-bars are secured to the heads, substantially as de- 1 scribed.

In testimony whereof I affix my signature in presence of two witnesses. Y
